Why Is My AC Not Running Properly This Summer? 

As the summer heat envelops Pittsburgh, having a reliable and efficient air conditioning (AC) system is essential for comfort and safety. However, it’s not uncommon for homeowners to experience issues with their AC units during the hottest months of the year. If you find yourself wondering, “Why is my AC not running properly this summer?” you’re not alone. Several factors can contribute to AC problems, from dirty filters to refrigerant leaks. Let’s explore some common causes and what you can do about them.

Answering The Question: Why Is My AC Not Running Properly This Summer? 

Dirty Air Filters

One of the most common reasons behind summer AC troubles is dirty air filters. Your AC system relies on unrestricted airflow to cool your home effectively. Over time, air filters can become clogged with dust, pet hair, pollen, and other debris. When this happens, the airflow through your ducts is restricted, forcing your AC system to work harder to push air through. This increased strain on the components can lead to overheating and reduced efficiency. Regularly replacing your air filters is a simple yet crucial maintenance task. During peak usage in the summer, it’s advisable to check and replace your filters every 30 days or less. Clean filters allow air to flow freely again, taking the pressure off your HVAC system and helping it run more efficiently.

Refrigerant Leaks

Refrigerant is the lifeblood of your air conditioning system, responsible for absorbing heat from inside your home and releasing it outside. When there’s a refrigerant leak, the level drops, making it harder for your AC to cool your home properly. Low refrigerant levels also cause strain on the compressor and condenser, as they have to work harder to function with less refrigerant. Refrigerant leaks are typically caused by wear and tear on AC components such as coils, valves, and seals. If you suspect a refrigerant leak, it’s important to have a professional technician inspect your system. They can identify the source of the leak, repair it, and recharge the refrigerant to the appropriate level.

Worn Out Parts

Air conditioners contain numerous mechanical, electrical, and structural components. Years of summer use can lead to wear and tear on parts like coils, compressors, motors, belts, valves, fuses, and switches. As components degrade over time, they become less efficient and will eventually break down, leading to intermittent cooling or total failure. Routine maintenance can help identify and replace worn-out parts before they cause significant problems. If your AC system is older, it might be worth considering a replacement, as newer models are more energy-efficient and reliable.

Improper Maintenance

Lack of regular preventative maintenance is a common cause of summer AC problems. Preventative maintenance tasks such as coil and filter cleaning, refrigerant level checks, leak inspections, part replacements, and lubrication help prevent issues. When you skip tune-ups and upkeep, parts wear out faster, and problems go undetected, escalating over the summer months. Proactive maintenance ensures your air conditioner can handle the demands of summer heat. Scheduling an annual maintenance check with a professional HVAC technician can save you from unexpected breakdowns and extend the lifespan of your system.

Electrical and Installation Issues

At the heart of your cooling system is a complex assortment of electrical components. Problems with wiring, motors, fuses, controls, and connections can significantly hinder your AC’s performance. Additionally, incorrect system sizing or ductwork that doesn’t optimize airflow can reduce efficiency and strain your AC. Electrical issues can be particularly tricky to diagnose and repair without professional help. If you think there is a problem with your electrical components or ductwork surrounding your system, it’s crucial to schedule a home duct performance test. This test can ensure your home is getting adequate cooling without putting too much pressure on your system.

Tips for Maintaining Your AC System

1. Keep the Outdoor Unit Clean: Ensure that the outdoor condenser unit is free from debris, such as leaves, grass clippings, and dirt. A clean unit can dissipate heat more effectively, improving overall performance.
2. Check the Thermostat: Sometimes, the issue can be as simple as a malfunctioning thermostat. Ensure your thermostat is set correctly and functioning properly. Consider upgrading to a programmable or smart thermostat for better control and efficiency.
3. Inspect the Ductwork: Leaky or poorly insulated ducts can cause cool air to escape before it reaches your living spaces. Have a professional inspect your ductwork for leaks and proper insulation.
4. Ensure Proper Insulation: Proper insulation in your home helps keep the cool air inside and the hot air outside. Check for any gaps or cracks in doors and windows and seal them to improve efficiency.
5. Use Ceiling Fans: Ceiling fans can help circulate cool air more efficiently, reducing the load on your AC system. Ensure your fans are set to spin counterclockwise during the summer to create a cooling breeze.
